2. Boost Converter The averaged circuit model of an ideal boost converter is shown in Figure Q2. The boost converter has L = 22 μH, C = 660 µF, rc = 30 m2, input voltage, va = 12 V, output voltage, V = 18 V, load resistance, R = 12 Q2, and switching frequency fs = 100 kHz. The circuit operates in continuous conduction mode. i₁ (1) (ii) (iii) Va SL (s) or + U₁ 7 + d'V₂ i₂ + √₂ d'l, + FI VER SC Figure Q2 By doing perturbation and linearization on the averaged circuit model, obtain AC small-signal model and DC steady-state model. Analyze DC steady-state model to determine all bias point constants. Analyze AC small signal model to obtain control to output transfer function, d (iv) Using LTSPICE to verify the small-signal model. You can do it by comparing the bode plot of control-to-output transfer function based on the small-signal model vs the small-signal PWM switch model. (v) Obtain the gain and phase of(s) at frequency of 5 kHz using manual calculation d and compare with the simulation.
